因为资源的限制，数学中的小数无法直接在计算机中准确表示。为了更好地表示它，计算机科学家们发明了浮点数，这是对小数的近似表示。维基百科中关于浮点数的概念说明如下：The term floating point refers to the fact that a number's radix point (decimal point, or, more commonly in computers, binary point) ...
The term floating point refers to the fact that a number's radix point (decimal point, or, more commonly in computers, binary point) can float; that is, it can be placed anywhere relative to the significant digits of the number. 也就是说浮点数是相对于定点数而言的,表示小数点位置是浮动的。

JEP 371introduces hidden classes in Java 15. Hidden classes have the following implications to existing code: Class::getNametraditionally returns a binary name, but for a hidden class it returns a string that contains an ASCII forward slash (/) and is therefore not a binary name. Programs tha...

Imaginary literals: The imaginary suffix i may now be used with any (binary, decimal, hexadecimal) integer or floating-point literal. Digit separators: The digits of any number literal may now be separated (grouped) using underscores, such as in 1_000_000, 0b_1010_0110, or 3.1415_9265. ...
World Time - Displays current time in different time zones around the world for easy global time tracking. Numeral System - Converts numbers between different numeral systems (e.g., decimal, binary, hexadecimal) for easy numerical conversions. ...
The term floating point refers to the fact that a number's radix point (decimal point, or, more commonly in computers, binary point) can float; that is, it can be placed anywhere relative to the significant digits of the number.
This notation works just fine, but we can make it a little more readable. Instead of writing a whole binary number for our mask, we can use the left bitshift operator (<<). it just shifts all digits to the left for a given number of places. For example: 1<<2 = B100, B101<<1...
